Problems solved by technology

[0003] At present, when using multi-camera cameras to track the target, the target images acquired by different camera positions will be different in angle, size and color, so that after processing the target images acquired by each camera position separately, the error It will be further expanded, which leads to a high probability of target detection errors and low detection accuracy

Abstract

The invention is applicable to the technical field of image processing, and provides a target tracking method and device, a computer device and a storage medium. The method comprises the steps of: acquiring a detection window of each frame image; performing normalization and region segmentation on each detection window according to the preset size, and extracting the eigenvalue of each sub-regionto compose the eigenvector of the object to be detected; determining a starting frame, a detection frame and a reference vector set according to a preset selection mode; calculating a similarity between a feature vector of a target to be detected and each reference feature vector in a reference vector set, and obtaining a maximum similarity; if the maximum similarity is greater than or equal to the first similarity threshold, determining that the feature vector corresponding to the maximum similarity and the reference feature vector belong to the same tracking target, and recording the changetrajectory of the tracking target according to the feature vector. The invention effectively reduces the error judgment rate of the target to be detected when the multi-position tracking target, and improves the target detection accuracy.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a target tracking method, device, computer equipment and storage medium. Background technique [0002] Object tracking is an important research branch in the field of computer vision, which has a wide range of applications in military guidance, video surveillance, intelligent transportation, robotics, and artificial intelligence. [0003] At present, when using multi-camera cameras to track the target, the target images acquired by different camera positions will be different in angle, size and color, so that after processing the target images acquired by each camera position separately, the error It will be further expanded, which leads to a high probability of target detection errors and low detection accuracy. Contents of the invention [0004] Based on this, it is necessary to address the above technical problems and provide a target tracking method, devic...
